2. INSTALLATION

2.1 Installation Site

To get the best results from your Henden heat pump, its location is critical. The Henden heat pump takes hot air from its surroundings and transfers this heat through its heat exchanger, to the pool water.

The Henden heat pump must be installed on a level surface. Henden recommends a concrete slab, or stable pavers that are detached from the foundations of the building. The Henden heat pump should not be installed in an enclosed space (e.g. under a deck, or in a shed).

The Henden heat pump is for outdoor installation only. To get the best performance from your unit, ensure 60cm of clearance around and 120cm above the Henden heat pump, see Image 1.

2.2 Bypass System

Although a bypass system is not necessary for your Henden heat pump to operate properly, we strongly recommend the installation of a bypass system to make the maintenance and winterising of the Henden heat pump easier.

Congratulations on the purchase of your Henden by Nirvana heat pump. It is designed and manufactured in Canada and is renowned for its efficiency and reliability.

In accordance with AS/NZS 60335.2.41 we are obligated to inform you that this Henden heat pump is not to be used by children, or infirm persons and must not be used as a toy by children. Please ensure young children are supervised to ensure that they do not play with the heat pump.

1. HOW IT WORKS

The Henden heat pump is equipped with a large surface evaporator that allows heat to be extracted from the surrounding air. This heat is transferred to the pool water by the titanium heat exchanger. This method generates substantial energy savings compared to: a conventional electric resistance heater; and natural, or propane gas pool heaters.

1.1 Important facts

• The Henden heat pump is designed to operate at water pressures ranging from 34kPa – 206kPa;

• The optimal water flow to maximise performance is 265L/min minimum flow is 160L/min;

• Your pool pump should always be on when the Henden heat pump is in operation.

Media Filter

For connections using a single pool pump:

• With your pool pump connected to your filter, connect the discharge line of the filter to the inlet connector located on the base of the Henden heat pump.

• Connect the pool water return line to the discharge connector located on the base of the Henden heat pump.

For connections using a secondary pool pump:

• Connect the pump discharge line to the inlet connector located on the base of the Henden heat pump

• Connect the pool water return line to the discharge connector located on the base of the Henden heat pump

Once all the connections have been made, turn the pool pump on to check water pressure and to ensure that all connections are watertight. The flow rate must be between 160L/min – 300L/min maximum. Correct water flow will ensure optimum performance and efficiency of the Henden heat pump. Optimum flow rate is 265L/min.

For use in conjunction with solar pool heating:

Should the Henden heat pump be used in conjunction with a solar pool heating manifold, the water entering the Henden heat pump should first run through the solar absorber. Do not plumb the solar absorber after the Henden heat pump. Henden doesn’t recommend this practice as solar absorbers can’t typically accommodate the same flow rates as the Henden heat pump. The solar absorber may also act to cool water rather than heating, in cooler weather. A better practice would be to run separate flow circuits.

For use in conjuction with a Henden Chlorinator:

Should the Henden heat pump be used in conjunction with a Henden chlorinator, the chlorinator cell is required to be installed after the Henden heat pump. If the chlorinator cell is installed before the Henden heat pump this will allow heavily chlorinated water to enter the Henden heat pump. This will significantly shorten the life expectancy of the Henden heat pump and may void warranty.

2.4 Electrical Connection

WARNING: The electrical connection should be done by a qualified electrician according to national, state and local city codes or standards. The unit should be connected to a compatible RCD (Residual Current Device).

2.5 Connecting a Henden H8VSPBT pump

The following section should be read in conjunction with the installation and operating instructions of the Henden H8VSPBT pump. This option requires the installation of a secondary relay.

To achieve maximum heating efficiency from the Henden heat pump, connect a Henden H8VSPBT pump using an RJ45 cable. When connected and the Henden heat pump detects your pool needs to be heated, it sends a signal to turn the Henden H8VSPBT pump to full speed (or an overridden speed selected by you). You will need to purchase a separate relay to accommodate this. Specifications of relay required:

• 24V AC coil;

• No contact;

• Contact current: 1A minimum;

• Screw contacts preferred as they can be connected to the RJ45 network cable used to signal the Henden H8VSPBT pump more easily.

Before placing a service call

There is always a possibility of condensation, especially on days with a high humidity level. If you see water near the heat pump, there’s a good chance it comes from condensation. To make sure it is water from condensation you can shut the heat pump off, leaving the pool pump running. Within a few hours, if you see that the water around the unit is drying up, it is indicative of normal condensation.

Before calling your installer or 1300 HENDEN (1300 436 336), follow the steps below;

1. Make sure the circuit breaker or isolation switch is ON, the fuses are functional and the heat pump is connected properly (green light on the unit).

2. Make sure that the pool pump is running at full capacity, has sufficient flow, and that the filter is clean.

3. Make sure that the water inlet and outlet are open and bypass valve is closed.

4. Check whether the temperature set is higher than the actual pool temperature.

5. Check that the plumbing is positioned in a way to enable sufficient water flow.

6. Check that the evaporator is not obstructed by pollen, leaves, grass, etc. (see maintenance for washing instructions).

7. When the temperature goes down to about 7ºC, the heat pump may switch to de-icing mode; it will then start a cycle that stops the compressor while letting the fan continue running. Once the cycle is complete, it will resume normal operation.

8. Frost may appear on the evaporator during cold weather and this is normal; however, if there is 12mm of ice or more on the evaporator, contact Henden immediately.

If your heat pump does not operate properly after following these steps, contact your installer or 1300 HENDEN (1300 436 336).

All replacements must be made using Henden parts to maintain your heat pump performance, durability and safety, as well as keeping your warranty valid.

WARNING DO NOT modify or remove a safety device. The manufacturer disclaims all responsibility if installation or maintenance instructions are not followed or if electrical or mechanical components and/or safety devices have been modified in any way.
